Estudio geotécnico in Caniles

In the municipality of Caniles, soils formed by shales and schists predominate, accounting for the largest proportion of the subsoil materials. These strata, together with compact gravels and sands, generally provide good bearing capacity for shallow or semi-deep foundations, depending on the thickness and degree of weathering. Limestones, dolomites and marbles, although less abundant, can offer high strength but require special attention if they occur fractured. The occasional presence of fine sands and silts usually does not significantly affect conditions, but their distribution should be monitored during field campaigns. Formations of low permeability govern natural drainage, which may affect projects where it is necessary to evacuate groundwater.

With regard to seismicity, Caniles presents a moderate level, with 18 events over the last 30 years and a maximum recorded magnitude of 4.5, which implies that this action must be taken into account in structural design. Given the presence of carbonate formations, there is a risk of karst-related phenomena; therefore, it is essential to check for the possible existence of cavities or dissolution processes before carrying out any foundation. Since the substrate is not clayey, the risk of ground expansivity is ruled out, leaving as the main controlling factors the verification of karst conditions and the impact of moderate seismicity in the design of buildings and structures.
